Among the species already known may be men-

 Humboldt and Bonpland in New Granada, and the 

 Hemiragis aurea (Lam.), End., which adorned the 

 trunks of trees with its great clusters. , . . 



The most precious of the Hepaticae are often, as

 In spite of that, he found some novelties, and among 

 them an unpublished genus, the Myrio-colea irrorata, 

 represented on Plate xxii. of his book, 1 which is 

 perhaps the most interesting that he has ever found. 

 It was growing on bushes watered by the stream

 forest of Canelos, and, as will be seen from his 

 book, they are very numerous. 



Banos lies just at the foot of Mount Tungu-
